The BNK (Test Drive Unlimited Data Package) file extension is a data package used to store audio, images, and videos in Test Drive Unlimited, an open world racing video game developed by Eden Games and published by Atari. The BNK extension allows the game to loop cut-scenes, load in-game menu soundtracks, and store user interface elements, such as loading screens. BNK files are usually found within the game's data folder.
Background and Usage
BNK files are compiled archives and can contain multiple audio or image files compressed in a single file supported by the XPR Toolsuite. This makes it easier for developers to manage and distribute their resources when programming their video game projects. BNK files can be opened on a PC by installing the XPR Toolsuite from Atari.
Alternatively, individual files inside of the BNK archive can be extracted by using a hex editor or disk editor such as HxD. Other similar file extensions include SBK, IBK, SNG, NVW, DBY and more.
Compatibility
The BNK file extension is primarily associated with Test Drive Unlimited and other associated PC titles developed by Atari. It is not recommended to open or manipulate BNK files outside of its intended software, as it may cause damage to the operating system and corrupt data that might be irreplaceable.
Programs for WINDOWS system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .BNK) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .BNK extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .BNK file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .BNK extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .BNK extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .BNK file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .BNK file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .BNK file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .BNK file) will be extended to the maximum.
It is also good to check
- if the .BNK file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
